Colloidal antimony pentoxide yog cov khoom siv hluav taws kub antimony uas tsim los ntawm cov teb chaws muaj kev lag luam thaum xyoo 1970. Piv nrog antimony trioxide hluav taws kub retardant, nws muaj cov yam ntxwv hauv qab no:
1. Cov tshuaj tua hluav taws kub colloidal antimony pentoxide muaj cov pa luam yeeb me me. Feem ntau, qhov ua rau tuag taus LD50 ntawm antimony trioxide rau nas (lub plab) yog 3250 mg / kg, thaum LD50 ntawm antimony pentoxide yog 4000 mg / kg.
2. Colloidal antimony pentoxide muaj kev sib raug zoo nrog ntau cov organic solvents xws li dej, methanol, ethylene glycol, acetic acid, dimethylacetamide thiab amine formate. Piv nrog antimony trioxide, nws yooj yim dua rau kev sib xyaw nrog halogen nplaim taws retardants los tsim ntau yam high-efficiency composite nplaim taws retardants.
3. Qhov loj me ntawm cov khoom me me ntawm colloidal antimony pentoxide feem ntau tsawg dua 0.1 hli, thaum antimony trioxide nyuaj rau kho kom zoo rau hauv qhov loj me ntawm cov khoom me me no. Colloidal antimony pentoxide yog qhov tsim nyog dua rau kev siv hauv cov fibers thiab cov yeeb yaj kiab vim nws qhov me me ntawm cov khoom me me. Hauv kev hloov kho ntawm cov tshuaj fiber ntau uas ua rau hluav taws kub, ntxiv cov gelatinized antimony pentoxide tuaj yeem zam qhov tshwm sim ntawm kev thaiv qhov tig thiab txo qhov muaj zog tig los ntawm kev ntxiv antimony trioxide. Thaum ntxiv antimony pentoxide rau qhov ua tiav ntawm cov ntaub, nws cov nplaum rau ntawm qhov chaw ntawm cov ntaub thiab qhov ua haujlwm ntawm cov hluav taws kub zoo dua li cov antimony trioxide.
4. Thaum cov nyhuv ntawm cov nplaim taws zoo ib yam, qhov ntau ntawm colloidal antimony pentoxide siv los ua cov nplaim taws retardant yog me me, feem ntau tsuas yog 30% ntawm antimony trioxide. Yog li ntawd, kev siv colloidal antimony pentoxide ua cov nplaim taws retardant tuaj yeem txo qhov kev siv antimony thiab txhim kho ntau yam khoom siv lub cev thiab kev ua haujlwm ntawm cov khoom nplaim taws retardant.
5. Antimony trioxide yog siv rau cov khoom siv hluavtaws uas tsis muaj hluav taws, uas yuav lom Pd catalyst thaum lub sijhawm electroplating thiab rhuav tshem cov pas dej plating tsis tau plated. Colloidal antimony pentoxide tsis muaj qhov tsis zoo no.
Vim tias colloidal antimony pentoxide nplaim taws retardant muaj cov yam ntxwv saum toj no, nws tau siv dav hauv cov khoom nplaim taws retardant xws li ntaub pua plag, txheej, resins, roj hmab, tshuaj fiber ntaub hauv cov teb chaws tsim. Cov engineers los ntawm Technology R & D Center ntawm UrbanMines Tech. Limited pom tias muaj ntau txoj kev npaj rau colloidal antimony pentoxide. Tam sim no, hydrogen peroxide feem ntau yog siv rau kev npaj. Kuj tseem muaj ntau hom hydrogen peroxide txoj kev. Tam sim no cia peb ua piv txwv: ntxiv 146 feem ntawm antimony trioxide thiab 194 feem ntawm dej rau lub reactor reflux, do kom ua ib qho slurry dispersed uniformly, thiab maj mam ntxiv 114 feem ntawm 30% hydrogen peroxide tom qab cua sov rau 95 ℃, ua rau nws oxidize thiab reflux rau 45 feeb, thiab tom qab ntawd 35% purity colloidal antimony pentoxide kua tuaj yeem tau txais. Tom qab cov tshuaj colloidal txias me ntsis, lim kom tshem tawm cov khoom tsis yaj, thiab tom qab ntawd qhuav ntawm 90 ℃, cov hmoov dawb hydrated ntawm antimony pentoxide tuaj yeem tau txais. Ntxiv 37.5 feem ntawm triethanolamine ua tus stabilizer thaum lub sijhawm pulping, cov tshuaj colloidal antimony pentoxide uas tau npaj tseg yog daj thiab viscous, thiab tom qab ntawd qhuav kom tau txais cov hmoov daj antimony pentoxide.
Siv antimony trioxide ua cov khoom siv raw los npaj colloidal antimony pentoxide los ntawm hydrogen peroxide txoj kev, txoj kev yooj yim, cov txheej txheem thev naus laus zis luv luv, kev nqis peev khoom siv tsawg, thiab cov peev txheej antimony raug siv tag nrho. Ib tuj ntawm cov antimony trioxide ib txwm tuaj yeem tsim tau 1.35 tons ntawm colloidal antimony pentoxide hmoov qhuav thiab 3.75 tons ntawm 35% colloidal antimony pentoxide kua, uas tuaj yeem txhawb kev tsim cov khoom siv hluav taws xob thiab nthuav dav cov kev cia siab ntawm cov khoom siv hluav taws xob.
